      Just carefully remove the windshield washer fluid reservoir to have a full clearance access to reach the battery.

      Replace the bank 1 sensor 1 oxygen sensor. This sensor is threaded into the outlet of the exhaust manifold at the rear of the engine by the firewall.

    Hard to start, then white smoke out of exhaust
    didn't drive car for 10days, then was hard to start. got started & heavy white smoke out of exhaust. Any idea what trouble could be?
    • Jimm

      The white smoke is not a good sign; more than likely - the cylinder head gasket has a leak due to the overheating.
      As the first step; perform a cooling system / radiator pressure test when the engine is cold - to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

    The car will not turn over at all it has power to everything but it wil not even attempt to turn tested starter its fine
    this is after i changed the steering column because the old one was loose and the right turn signal had quit working. everything else was fine until i Changed out the steering column.
    • HouseCallAuto

      You have a security / anti-theft issue going on. You can't just switch steering columns, they are not plug and play. Try this first:

      Do the automated learn 30 minute procedure as follows...

      1. Insert your key into the ignition lock cylinder.
      2. Turn the ignition switch to the RUN position. The SECURITY indicator illuminates for the length of the auto learn timer (10 minutes).
      3. When the auto learn timer expires and the SECURITY indicator turns OFF, turn the ignition switch to the OFF position. Remove the key.
      4. Wait 10 seconds.
      5. Repeat steps 1–4 twice for a total of 30 minutes.
      6. Insert the newly learned key into the ignition lock cylinder. Turn the ignition switch to the RUN position. The SECURITY indicator remains OFF. This indicates that the new ignition key was learned.

    Whitish smoke from exhaust
    120,000 miles. car not driven for 10 days, was hard to start, then heavy whitish smoke coming out of exhaust. any idea what trouble is?
    • HouseCallAuto
      9/29/2013 HouseCallAuto
      Depends on how much white smoke. You may be burning coolant as a result of a bad head gasket or maybe you are overreacting to normal condensation / humidity smoke.
      9/30/2013 emailforjeannie
      Thanks! Do you know, is the head gasket very costly to replace?
    • HouseCallAuto
      9/30/2013 HouseCallAuto
      Yes it is, more than $1000 so if it is a head gasket you would really have to be attached to this car and want to keep it after paying for that.

    When accelerating,car hesitates and spits and sputters until I give it more gas.after a momentary lag it finally catches
    And accelerates.then it seems to not want to shift until I ease up on the pedal a bit.when it doesn't shift the RPM's climb but the speed doesn't increase.also when I kick it down to the passing gear to accell it holds the gear to long and Doesn't go much faster

      Have someone hook up a scanner to see if the vehicle has any trouble codes and go from there.
    • Jimm
      9/30/2013 Jimm
      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

      You'll have to be more specific as to what type of noise your hearing.
      Is it a knock, tap, or even an exhaust leak?

    Remove radiator for repair
    • Jimm
      9/18/2013 Jimm
      First step, drain the coolant from the radiator. Use the drain petcock (valve) on the underside of the radiator. If no drain, then simply remove the lower hose connection.

      Next, remove the upper and lower hose connectons at the radiator. Then, remove the transmission cooling lines / fittings at the radiator. Finally, remove the radiator mounting bolts and lift the radiator out.

      Replacing the catalytic converter will knock down all the numbers. Only other thing just to mention is make sure that the fuel filter has not been forgotten about for a few years as they do get clogged up to where you can't hardly blow through them after removing it and it can cause an emission failure, however if you have memory of replacing it within the last 25K miles then its still OK.

      Have you seen if the engine is reaching proper temperature. You might try changing the
      thermostat. It could be keeping it from reaching closed loop.+

      You have to make clear. Is there ignition spark yes / no? Is there injector pulse yes / no? One side of the injector should have battery voltage with key on (PINK). Did you replace the crank sensor?
